I think the latest plans for the JRTC (which apparently are financially feasible in the next 5 years) will go a long way to facilitating the connections needed to/from intercity rail. The key is getting AAF and Amtrak to locate at the Prime Osborn.
Sorry, but the new plans for the JRTC are just as F**ked up as the previous ones. They spun the Greyhound station around and slid the whole mess one block closer to what will be a huge, abandoned, railroad depot-convention center site. RS&H, FDOT or JTA, whoever is responsible for this gigantic 'transit republic' seem to have no concept for a SINGLE - ONE STOP - BUILDING serving as a transportation center. Note that JIA does not have separate terminals for each airline and for the buses and cabs, "all connected with a convenient elevated moving sidewalk."
Since they haven't a clue, neither do our local 'leaders' all of whom seem to have had very little experience using transit in a truly transit friendly city. The JRTC 2.0 is just the latest epic fail in the making.
